OK this is first hand info from Nissan to a friend of mine and I.
The problem was introduced in 2000 as gearboxes were revised Truckster.... Nissan revised the gearboxes when they introduced the 3.0L model.
On that revision, the people who manufacture the gears for Nissan stuffed up on the tolerances, not all vehicles were affected, the problem was resolved by 2002.
3.0L ones were more affected only because they have lower diff ratios and owners select 5th earlier.
This friend of mine did not tow and had a 4.2 but admitted that remained in 5th below 80kms/h. His Patrol was used normally, was not a city vehicle nor 100% highway.
Series1 Patrols should not be affected and series 3 patrols should not be affected.
Off course with any gearbox, do not "torque" the gearbox in fifth as that gear is not strong and that is common on all motor vehicles.
By design 5th gear is not part of the main set, sits on one side and has very small gears/teeth to keep it quiet at high speeds.
As a rule change to 4th while up
hill below 80kms/h.
